#
# This file provides escape code options for adding color to echo and
# printf script commands. Source this file as necessary. Add additional
# colors if desired.

# Sourcing this script allows writing scripts with human readable
# color references rather than embedding the actual raw escape codes,
# which few people remember or know. A human readable variable enables
# a person to read a script and know the intended color.

# Write a script to include the human readable color code variables.
# Example:
# echo -e "${BOLDRED}This is a warning message!${COLOR_RESET}"
# echo -e "${BOLDWHITE}Your network interface is: ${BOLDGREEN}eth0${COLOR_RESET}"

# When this script is sourced and run, the $COLORED_SCRIPT variable will
# determine whether the end-user sees color. For example, people running a
# server might care less about colored scripts, but people running desktop
# boxes likely will want otherwise.

# Modify this variable to produce the desired effect:
COLORED_SCRIPTS=yes

ESC="\033["

# This color scheme looks good with a black background.
# Feel free to modify for other background color schemes.
